Origin: PG [a word of Pre-Greek origin]X [probably]

Etymology: Of the presents κναίειν, κνῆν, κνήθειν the last can be an innovation to κνῆ-σαι etc. after πλῆ-σαι: πλή-θ-ω, λῆ-σαι: λήθ-ω a. o. The pair κνῆν: κναίειν agrees with the semantically close ψῆν: ψαίειν. - One compares several words with initial IE. * k(e)n- but with different forms, which is not surprising in view of the emotional value of expressions for `scratch, grate'. With κνῆ-ν (prob. orig. athematic; Schwyzer 675f., Chantraine Gramm. hom. 1, 297 a. 307) from IE. * knē- agree best in Baltic and Germanic Lith. kn(i)ó-tis `peek (oneself) off, get loose', OHG nuoen `make smooth by scratching, fit exactly' (with OHG hnuo `joint, groove' etc.) from IE. * knō-? (cf. κνώ-δ-αλον?), perh. * knā- as in Alb. krromë `scab, mange' form IE. *knā-mn̥ (Gr. κνῆμα is independent). Lat. cnāsonas however, acc. pl. `scratching nails' (Paul. Fest. 52) from hell. *κνά̄σων `scratcher' ( κνᾶσαι ὀλέσαι, λυπῆσαι H.); cf. Leumann Sprache 1, 207. - The - αι- in κναίω however has no direct counterpart (Lith. knaisýti is secondary to knìsti `scratch', s. κνίζω). Connecting κνῆ-ν and κναί-ειν to an old paradigma (* knē[i]-mi: knǝi-mé (Schwyzer 676; cf. Specht Ursprung 325; the last form is impossible since the laryngeal theory) is quite hypothetical. - Cf. κνίζω, κνύω, κνάπτω; κνώδαλον, κνήφη, κνέωρος and κόνις; s. Pok. 559ff., Fraenkel Lit. et. Wb. s. knablỹs. - Strangely enough it has not been proposed that the words could well be Pre-Greek; the meaning makes this quite possible; the connections in Pok. 599 are far from convincing. Cf. also κναδάλλεται κνήθεται H., with which compare γνάφαλλον, γνόφαλον, which are clearly Pre-Greek (s.s.v. κνάπτω); is κναδ- a variant of κνηθ-? For κναδ- no PIE prefrom can be reconstructed (cf. on γνάθος). Note that Kuiper assumed that words with kn- in Germanic were prob. substrate, NOWELE 25 (1995) 68 a.70. The formation of κνήσων (and the Latin loan cnāsōn- cited above) seems non-IE; cf. DELG s.v. Also the formation of a verb in - αίω is unknown.

Derivatives: κνῦμα n. `scratching (Ar. Ek. 36, Gal. 19, 112) and `scratch': κνύος n. (Hes. Fr. 29, 1), κνῦσα f.

Etymology: Wie zu den sinn- und lautähnlichen κναίω, κνῆν, κνάπτω, κνίζω kann man auch zu κνύω aus den verwandten Sprachen, namentlich aus dem Germanischen und Baltischen anklingende Wörter heranziehen: ahd. hniuwan `zerstoßen, zerquetschen', mit ausgehendem Dental awno. hnjōđa `stoßen, schlagen, nieten', beide idg. qneu-, lett. knūdu und knūstu `jucken'. Weitere Formen m. Lit. WP. 1, 396f., Pok. 562f.; vgl. noch de Vries IF 62, 142f. Schwyzer 676 will für κνύω (wie entsprechend für κνῆν, κναίειν) ein altes ablautendes Wurzelpräsens *qnṓu-mi: *qnū̆-me ansetzen.
